摘要
促分裂原活化蛋白激酶(mitogen-activated protein kinases,MAPK/MPK)级联是植物响应外界环境变化的重要信号传导途径。MAPK级联参与植物低温信号转导过程并在此过程中起信号放大和传递的中枢作用。目前人们在植物中发现多种参与低温胁迫过程的MAPK。本文介绍了植物中与低温胁迫相关的MAPK研究进展,并通过生物信息学的方法对番茄中具有相关功能的番茄促分裂原活化蛋白激酶(LeMAPKs)进行预测,为进一步研究MAPK级联在植物低温信号转导过程中的作用机制提供参考。
Mitogen-activated protein kinase（MAPK） cascade is an important pathway of signal transduction in plants to response the changes from external environment.MAPK cascade is involved in the process of low-temperature signal transduction and plays a dominant role in the amplification and transmission of signals.Currently,different MAPKs are discovered to be involved in low-temperature stress in plants.Research progress of MAPK was discussed in this article.Bioinformatic methods were also applied to predict relative functions of LeMAPKs in tomato.Therefore,this article provided the theoretical basis for further investigation on MAPK cascade mechanisms of signal transduction at low temperature.
